基于Web的近实时洪水事件可视化和损失估计（洪水EViDEns）是通过卡拉加州立大学的Phil-LiDAR 1项目开发的在线地理可视化应用程序。该应用程序的目标是由菲律宾棉兰老岛卡拉加地区的地方政府单位和社区使用，以帮助他们在发生洪水灾害时做出地理空间方面的知情决策。该应用程序融合了网络地图技术、各种地理空间数据集，包括激光雷达衍生的高程和信息产品、水文气象数据和洪水模拟模型，以近实时地可视化当前和未来可能的洪水程度及其对基础设施的相关损害。Flood EViDEns应用程序通过由网络地图和表格组成的用户友好的前端界面，促进了这种近乎实时的洪水相关信息的发布和利用。该应用程序的后端由运行洪水模拟模型和地理空间分析的计算机组成，以动态地（以自动化的方式）产生当前和未来的洪水范围，以及受洪水影响的结构的列表信息，包括灾害类型。这些输出被转发到PostgreSQL/PostGIS空间数据库，在那里它被访问的前端接口的网络可视化。洪水EViDEns提供的信息对地方政府部门和社区非常重要，因为它可以提高公众对即将发生的洪水灾害的认识和反应能力。在强降雨事件期间提供这种信息是有用的，因为它可以帮助准备疏散，容易地确定需要立即采取行动的区域，确定应该避免的区域，以及估计随着洪水的发展对人员和基础设施造成的损害的严重程度。
The Web-based Near-real Time Flood Event Visualization and Damage Estimations (Flood EViDEns) is an online geo-visualization application developed through the Phil-LiDAR 1 project of Caraga State University. The application is targeted to be utilized by the Local Government Units (LGUs) and communities in the Caraga Region, Mindanao, Philippines to assist them in geospatially informed decision making in times of flood disasters. The application is an amalgamation of web mapping technology, various geospatial datasets including LiDAR-derived elevation and information products, hydro-meteorological data, and flood simulation models to visualize in near-real time the current and possible future extent of flooding and its associated damages to infrastructures. The Flood EViDEns application facilitates the release and utilization of this near-real time floodrelated information through a user-friendly front end interface consisting of web map and tables. The application's back-end consists of computers running flood simulation models and geospatial analysis to dynamically produce (in an automated manner) current and future flood extents, and tabulated information on the structures affected by flooding including hazard types. These outputs are forwarded into a PostgreSQL/PostGIS spatial database where it is accessed by the front end interface for web visualization. The information provided by Flood EViDEns is very important especially to the LGUs and the community as it can increase awareness and responsiveness of the public to the impending flood disaster. Providing this kind of information during a heavy rainfall event is useful as it could assist in preparation for evacuation, in easily identifying areas that need immediate action, in identifying areas that should be avoided, and in estimating the severity of damage to people and infrastructure as flooding progresses.
